Chinese Drywall: Foul Smelling, Yes. Health Effects Unclear

The scores of Florida homeowners seeking some conclusion whether the foul smelling Chinese drywall in their homes is harmful to their health will have to wait.

On Monday, Florida’s health department said preliminary tests show there’s no “specific” health hazard associated with the sulfur-based gases coming from the drywall, but the agency is conducting additional tests

“It’s not that we are saying it’s safe,” Florida toxicologist David Krause told reporters on a conference call on Monday. “We are moving forward on a much more detailed in-depth’’ study.

The test results released by the state health department on Monday did make one, definitive conclusion: Chinese-made drywall contained strontium sulfide, a material that’s known to have the odor of hydrogen sulfide in moist air. The U.S-made drywall did not contain this material.

The most common evidence of Chinese drywall problems is the corrosion of air conditional equipment, which is turning black and failing repeatedly. Homeowners have also complained about respiratory problems they believe are connected to the drywall.

The number of homeowners complaining about drywall odors to the Florida health department has swelled to about 150. Florida health officials have also spoken with health officials in Louisiana, North Carolina, Alabama and Washington, after learning that homeowners and home builders in those states were experiencing similar problems.

Meantime, for those experiencing health concerns or electrical problems they believe are associated with their drywall, Mr. Krause suggested that homeowners contact a physician or an electrician.

Mr. Krause said the additional tests could take several months to complete. “This is a very complex situation,’’ Mr. Krause said.
